This paper analyzes the effectiveness of the reaching law approach for sliding mode control of discrete time systems. The method is extended for sliding mode control for multi-input multi-output (MIMO) systems. Modified reaching law for reducing the chattering is proposed. The performance of the proposed controller is analyzed by carrying out simulation(More)
H∞ based sliding mode control has several advantage viz. fast response, robustness to parameter variation and disturbance rejection ability. Inverted pendulum qualifies as a benchmark system to test the suitability of controller design for under-actuated, nonlinear unstable system. In this context, H∞ based integral sliding mode controller is(More)
Fre Flight concept is a new air traffic management paradigm that has been proposed by the avionics community to solve the problem of air traffic congestion. But the greatest challenge in realizing such a concept is conflict detection and resolution during the free flight of aircraft. In present scenario, during any conflicts or disturbances, the autopilot(More)
Sliding mode controllers are known to be robust to parameter changes, disturbances and uncertainties. In this paper a novel discrete time sliding mode controller with two surfaces is proposed to improve the speed of response. Here, approach angle reaching law is used to take the trajectory to the surfaces. The advantage is that the system trajectory is(More)
The abstract is given below. Doctoral Committee members, members of the faculty, research scholars and other students are cordially invited. Abstract The development of techniques for the compensation of linear multivariable systems in the presence of uncertainty is of practical importance, where the dynamical behavior of the system is expressed in the form(More)
